The internet, as we know it, runs on DNS, the Domain Name System. Every time a user visits your website, their browser makes a DNS query to convert your domain (e.g., example.com) into an IP address. Historically, these DNS queries have been unencrypted, exposing them to snooping, tracking, and potential manipulation.
Enter DNS over HTTPS (DoH). This evolving standard encrypts DNS requests, shielding them from third parties and increasing user privacy. But what does this mean for domain owners and website operators? How does it impact your users' experience, and should you do anything to support it?
In this article, we break down DNS over HTTPS and explore its implications for domain privacy, branding, and the broader internet ecosystem. What Is DNS Over HTTPS (DoH)?
Traditionally, DNS queries are sent in plaintext. This means:
- ISPs can log your users’ browsing habits
- Network admins can intercept or block DNS lookups
- Hackers can potentially hijack DNS responses (a.k.a. DNS spoofing)
DNS over HTTPS encrypts these requests using the HTTPS protocol. Instead of using port 53 (standard for DNS), DoH uses port 443, the same as regular HTTPS traffic.
- DNS queries become part of encrypted web traffic
- They are hidden from prying eyes (including your ISP)
- Man-in-the-middle attacks are significantly harder
Why It Matters for Domain Owners
While DoH is largely implemented on the user/client side (browsers, OS, apps), it has significant implications for domain owners:
1. Enhanced Trust and Security Perception
When users feel protected, they are more likely to trust your domain. Supporting privacy-focused practices helps your brand align with modern expectations around:
2. Reduced DNS Tampering
DoH protects your domain's DNS queries from:
- Censorship by governments or networks
- Malicious DNS redirection attacks
- Injection of ads or phishing redirects
This ensures users always reach your real website, not a spoofed or hijacked version.
3. SEO and Reputation Benefits
Google and other search engines increasingly favor:
- Site integrity and performance
While DoH is not a direct ranking factor, a privacy-forward infrastructure supports your site’s overall credibility.
DoH vs. DNSSEC: What's the Difference?
It’s easy to confuse DoH with DNSSEC (Domain Name System Security Extensions). Both enhance DNS security, but in different ways:
- DNSSEC protects DNS data at the source, ensuring it hasn't been tampered with before reaching the user.
- DoH protects DNS in transit, encrypting the query between the client and resolver.
For maximum security, domain owners should support both:
- Enable DNSSEC on your domain (NameSilo offers this for free)
- Use a reliable DNS provider that supports DoH
Should You Implement DoH for Your Domain?
As a domain owner, you don't directly control whether users use DoH; that happens in browsers and operating systems. However, you can:
1. Choose DNS Providers That Support DoH
If you use a managed DNS service or CDN (like Cloudflare or Google DNS), ensure it supports DoH. This ensures compatibility with:
- Firefox and Chrome browsers
- Android and iOS DoH clients
- Enterprise security tools
2. Educate Privacy-Conscious Users
If your audience is tech-savvy or privacy-focused (e.g., developers, crypto users, journalists), highlight that your DNS provider supports DoH. This could be a trust-building point.
3. Combine DoH with HTTPS and DNSSEC
Create a layered security posture:
- HTTPS: Encrypts web traffic
- DNSSEC: Authenticates DNS records
- DoH: Encrypts DNS lookups
This trifecta positions your domain as safe, secure, and modern.
The Broader Privacy Context
DoH is part of a larger movement toward internet privacy:
- Browsers are phasing out third-party cookies
- Google and Apple are pushing for private relays and DNS protections
- Governments are exploring regulations around encrypted web data
Being proactive as a domain owner keeps your brand ahead of the curve and avoids being perceived as outdated or careless.
Challenges and Criticisms
Some network administrators argue that DoH:
- Makes content filtering harder
- Breaks internal DNS policies
- Shifts power to a few large DNS resolvers
These are valid concerns, especially in corporate or parental control environments. However, from a public internet and user-rights perspective, DoH represents a net gain for transparency and safety.
Conclusion
DNS over HTTPS is changing how the internet handles one of its most fundamental processes. While implementation is mostly browser-side, domain owners still play a vital role.
By understanding how DoH works and aligning with secure DNS providers, you can:
- Strengthen your brand trust
- Future-proof your web infrastructure
In an age of surveillance and spoofing, encryption isn't just nice to have; it's essential.
